ismy catch can setup right? its on a 2001 camaro. it seems ever since i put my catch can on, it now wont idle. on hot or cold startups, it takes a while to break into a steady idle and will sometimes die if i dont give it gas. could this be a pcv problem. it seems that right after i got it tuned, it ran perfect tho. and then the night after getting it tuned, i did the catch can and im thinking thats what caused it.

The catch can looks correctly hooked up with your PCV system. But did you check the lines in the back? they tend to crack back there. If it is damaged, I would do the LS6 valley cover swap and clean up the PCV lines.

I thought the 2001 came with the LS6 valley cover

nope, or at least mine didnt, although my 2001 did have 853 heads, ls6 intake, and a steel driveshaft...wierd

01-02 f-bodies came with LS6 intake manifolds, not the valley cover. The valley cover is under $100 and can easily be installed, there are two different LS6 VC, if you do the swap, make sure to get the newer design for the cleanest looking install.
ls1howto has a good write-up, but I believe it has the old p/n

FWIW, I have read that PCV issues can mess with the car's idle. I have an LS2 now so I plan to set mine up like this:

...You could do the same set up with the LS6 valley cover.

yes but its a bit involved. you need to install an LS6 valley cover. check here:

Still not sure what's the best setup, but mine's the same as yours and seems to be working well. Make sure it's doing it's job though.

You should be able to blow through the whole system with the hoses disconnected from the back valve cover hose, through the can and the valve and out the back TB hose freely with no leaks in between. You shouldn't be able to blow through from the rear TB hose into the can if you're using a PCV valve. At least that's my understanding. Is your valve backwards???

I've tried both setups, this works best for me. I currently have the LS6 VC nipple blocked. Both rear valvecover hoses meet at a barbed brass tee, then into the top of the can. All of the stock crappy lines have been replaced with fuel line. It catches a decent amount of oil.

A blocked PCV system will cause a low idle.
A leaking PCV system will cause a high idle.

looking at your pic, it looks like my pcv could be put in backwards. ill check. i dont really want to do the ls6 valley cover because i dont think i get much blow by if any with my new motor, but just wanted a catchcan just in case

I think that could be it. I have the same can as you, and I have the fat end of the PCV valve mounted directly on the catch can barb, and the hose going from the thin end to the intake.

i switched it around, but its no different. is there any way i can just delete this pcv garbage

Check the valve at the bottom of the catch can, all the way out is closed and all the way in is wide open. Kinda backward but the way the valve works.

I ran a breather for awhile. I got tired of smelling the fumes and it leaked a tiny bit when I flogged the car. Contaminates aren't evacuated, so you'll be changing your oil frequently.

Did you blow through the system to see if it's working one way only?

i had the issue when i did my ls6 valley cover, blow through your valve and see which way is blocked and which way you can blow through, you want the crank pressure to be relieved into your catch can
